TL;DR: Primers can be combined in a single PCR reaction providing a rapid, sensitive and straightforward method of species identification, and only small quantities of DNA are required, leaving most of the mosquito to be used for other analyses.

TL;DR: This work shows striking parallel phenotypic divergence between populations of the rocky‐shore gastropod, Littorina saxatilis, occupying contrasting habitats exposed to either wave action or crab predation, and provides new insight into a major model of ecologically driven speciation.

TL;DR: The repeated occurrence of partially reproductively isolated ecotypes and the conflicting patterns in neutral and selected genes can either be explained by separation in allopatry followed by secondary overlap and extensive introgression that homogenizes neutral differences evolved under allopate, or by repeated evolution in parapatry, or in sympatry.

TL;DR: It is argued that speciation research, both empirical and theoretical, needs to consider both the origin of barrier effects and the ways in which they are coupled, and for an extended view of reinforcement that includes coupling processes involving enhancement of any type of additional barrier effect as a result of an existing barrier.
